Oh yes, another one of my pet peeves with Raspberry Pi: ancient slow SD implementation.

SD Express can do up to 985 MB/s.
SD UHS-II @300MB/s would be plenty for most SBCs.
- gjsman-1000 7y agoDo be aware that the Pi 4 increased the SD Card Reader speed, almost by double, I hear.
- vardump 7y agoSure, but I still can't even use my 5-6 years old Samsung Pro microsd 64 GB card at full speed, 90-100 MB/s read & write!
- dfox 7y agoBear in mind that SD Express is SD only in name and otherwise it is just an NVMe in SD form-factor. And how much UHS-II is still an SD is somewhat questionable.
- vardump 7y agoTrue. But on the other hand similar to how for example USB standard has developed from USB 1.0 to USB 4. While it would technically be correct, no one says new USB standard X is USB in name only. Perhaps every data transfer interface standard eventually adopts a PCI-e lane. :-)
